Abstract:

A high pressure liquid cell interferometer to measure the variation of refractive index of liquids with pressure to 14 kbars has been constructed. The amount of liquid needed is only 3 c.c. Interferometric measurements have been carried out on twelve liquids with widely varying molecular size, shape and structure. These studies show 1 first experimental proof that the Eulerian frame-indifferent analogue strain E is a more useful strain measure than the Lagrangian strain, 2 Keanes equation of state best describes each and all liquids studied, 3 change in refractive index vs. E is linear for all liquids, even though the volume strain involved is as high as 33. This conclusion appears to be valid for all the liquids studied thus far. Author
